Bacterial diversity of the corals A. hemprichii and P. verrucosa across impacts. Samples were collected after 21 months of reciprocal transplantation across different impacts (“Unimpacted”, “Local wastewater and nutrients”, “Municipal sewage and sedimentation and oil”) near Jeddah, Red Sea and are displayed by destination impact. a Chao Index of bacterial richness, b Simpson Index of bacterial community evenness, c Shannon Index of bacterial diversity. Boxes of box plots represent the 25th to 75th percentile, lines show medians, error bars represent smallest/largest values to a maximum of 1.5 * IQR. N of each group indicated in a, Kruskal–Wallis tests significance level: **p < 0.01. Source data are provided as a Source Data file
